RE: [Javaserver-perl] Re: JavaServer dies when under heavy load

[Shao M. <sha...@si...>]

 
Hi to all,

Haven't had time to troubleshoot the issue, will be doing in the next few
days.
But one quick question came to mind, what are the preferred JVM you guys are
using for your linux box? And if I do not need the Java2 features ... Is
1.3.x series a better choice than 1.4.x?

Cheers!

Hey Shao,
    I would recommend running JavaServer under a profiler or debugger to see
better what's going on.  Does the JVM crash?  Does JavaServer hang?  Is
there a stack trace?
    Of course you can create a simple shell watchdog script to restart
JavaServer if it goes away but better to find out the root cause - I cannot
think of a reason why JavaServer would crash under heavy load from 24 users
unless there's a memory leak or you run out of system resources somewhere.
Of course there could be a JVM bug or any number of things that causes this.
    & please write to the list 'jav...@li...'

    thanks!
